ARTERIES (CARRY BLOOD AWAY FROM THE HEART)
AORTA	The main artery running above the heart & through the thorax, abdomen & pelvis
CORONARY ARTERIES	The vessels which supply the heart
AORTIC ARCH	Junction of the aorta giving rise to 2 large branches: the brachiocephalic trunk & left subclavian artery
COMMON CAROTID ARTERIES	Branches of the brachiocephalic trunk that supply the head
RIGHT SUBCLAVIAN, AXILLARY & BRACHIAL ARTERIES	Continuations of the brachiocephalic trunk which supply blood to the right forelimb
LEFT SUBCLAVIAN, AXILLARY & BRACHIAL ARTERIES	These arteries supply the left forelimb
SPINAL ARTERIES	As the name implies, these arteries supply the spine
COELIAC ARTERY	This artery supplies blood to the stomach, liver & spleen
CRANIAL MESENTERIC ARTERY	Supplies the small intestine
CAUDAL MESENTERIC ARTERY	Supplies the large intestine
PAIRED RENAL ARTERIES	Supply the kidneys
PAIRED OVARIAN/SPERMATIC ARTERIES	Supply the genitalia
EXTERNAL ILIAC & FEMORAL ARTERY	Supply the hind limbs
INTERNAL ILIAC ARTERY	Supplies the pelvic viscera
MEDIAN SACRAL ARTERY	Supplies the tail

VEINS - CARRY BLOOD TOWARDS THE HEART
JUGULAR VEINS	Drain the head
BRACHIAL VEINS	Drain the forelimbs
CEPHALIC VEINS	Drain the forelimbs
ANTERIOR VENA CAVA	Empties blood from the head and forelimbs into the right atrium
AZYGOUS VEIN	Drains blood from the intercostal spaces, and may either join the anterior vena cava or empty independently into the right atrium
POSTERIOR VENA CAVA	Empties blood from the abdomen, pelvis and hind limbs into the right atrium
BRACHIAL VEINS	Drain the hind limbs
FEMORAL VEINS	Drain the hind limbs
SAPHENOUS VEINS	Drain the hind limbs
